&lt;p&gt;&lt;b&gt;New page&lt;/b&gt;&lt;/p&gt;&lt;div&gt;What's an achromatic lens?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;An achromatic lens or Achromat is a lens that is created for the purpose of limiting the effects of lens(chromatic and spherical) aberration. Achromatic lenses are adjusted to attract two wavelengths to concentrate in the exact same plane.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;What's a chromatic aberration?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Chromatic aberration, also Called chromatic distortion and spherochromatism, is a result caused from dispersion as a result of failure of a lens to focus all colours to the same convergence point. When white light passes through glass, every wavelength element of this light is separated and concentrates at several points onto a plane. Chromatic aberration seem as &amp;quot;fringes&amp;quot; of color along borders that separate bright and dark parts of the image, due to each color in the optical spectrum can't be focused at a single common point.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;What's a spherical aberration?&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Spherical aberration is an Optical effect which happens in a lens due to the increase of refraction of light rays as soon as it strikes the lens. The produced image will result in imperfection. Both this phenomenon signifies that the lens is not working normally.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Achromatic double lenses&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Achromatic doublet is your Most frequent type of achromat lens. Generally, it consists of 2 individual lenses made from glasses with various amounts of dispersion.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Achromatic lenses use two Different glass materials of distinct dispersion to refocus the individual wavelengths of light into a single focal point.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Achromatic lenses may be Used to adjust the line of sight and focus laser beams. These lenses are widely utilized in high quality digital imaging, surface inspection, and spectroscopy applications.&amp;lt;br&amp;gt;&amp;lt;br&amp;gt;Shanghai Optics Specializes in manufacturing high precision custom Achromatic doublet lenses According to client's specifications.
